Hi all! I have a question regarding HTB and setting rate in a gigabit network. Issue is that full speed cannot be achieved when using HTB. Network speed is 2.2Gbit and through HTB it goes only up to 1.4Gbit. I was able to work around this issue by offsetting i.e. choosing a higher rate than my network speed (4Gbit) which then allowed my full speed (2.2Gbit). This higher rate was calculated by benchmarking. It's a minimum rate at which I could get full speed through HTB. Here is a simpler version of my setup used for debugging this issue: tc qdisc del dev eth0 root tc qdisc add dev eth0 root handle 1: htb default 100 tc class add dev eth0 parent 1:1 classid 1:100 htb rate 4000mbit ceil 4000mbit tc qdisc add dev eth0 parent 1:100 handle 100: sfq Note that I'm using an older kernel, it seems this issue was detected and fixed here: https://github.com/torvalds/linux/commit/1c0d32fde5bdf1184bc274f864c09799278a1114 I will upgrade the kernel, but wanted to check if this workaround makes sense in the meantime? Thanks, Dino
